To all whom it may concern Be it known that l, MAX Jnsrnn, a citizen of Germany, residing at Berlin, Germany, have invented a new and improved Safety- Closure for Containers ot inflammable Liquids, of which the following is a specification.

This invention relates to a safety closure for bottles, jars, cans and similar containers The closure is adapted to be fitted into the mouths of such containers as are provided with but a single ingress and egress opening, so that it permits the pouring in as well as the pouring out of the liquid. The construction should be such that the closure cannot be readily removed by unauthorized persons. So also the closure should effectively prevent the blame from striking inward, for which purpose it should be made to effectively conduct the heat generated, which latter purposeis rendered more ditlicult by the location of the closure within the mouth of the container.

The invention comprises essentially an elongated wire net which is titted into the mouth of the container conjointly with a metal body of a relatively large size, which besides constituting a heat conductor, also serves to attach the net to the container.

111 the accompanying drawing: Figure 1 is a longitudinal section of part of a con tainer embodying my invention; Fig. 1 a similar section showing the container in side view; Fig. 2 a plan on a reduced scale; Fig. 3 a detail of the tongues for removing the closure; and Fig. at a side view partly in section of a modification of the invention.

Referring more particularly to Figs. 1, 1 and 2, the letter A represents the neck of a bottle, jar, can or other container of inflam mable liquids. Into this neck is fitted a toraminated or small meshed wire tube or elongated sack a, tapering toward its bottom, while the upper end of the tube is open. Tube a is surrounded by a cylindrical metal shell I; to which it is suitably secured at its upper end in a heat transmitting manner. Shell 1; has an upper flaring section or head 0 and is provided below said section with a plurality specification of Letters Patent.

of upright slits d. The strips formed by these slits are bulged outwardly to constitute a plurality of convex resilient lamellae 0. Head 0 prevents the device from being pushed into the bottle neck to an undue ex tent, while lainellae c prevent it from dropping out said head and. lamella engaging; the vessel respectively above and below a contraction formed within the bottle neck. llithin the mouth of tube a is fitted a thimble shaped wire frame a which may be soldered or otherwise secured to the tube. This frame prevents the tube from being broken by the introduction ot a tunnel, and also constitutes a means for the withdrawal of the device from the bottle. This withdrawal is effected by tongs t (Fig. 3) having notched jaws u that are projected into the frame to engage diametrically opposed sections 3 thereof, so that by a pull on the tongs, the device will become unsealed against the action of the resilient strips c.

As shown in Fig. l, there may be fitted into the wire tube a, an inner toraminated sheet metal tube 1, which serves to protect tube (1 and also constitutes an ellicient conductor of heat.

It is obvious that changes may be made in the construe-tum ot the safety device Without departing from the spirit of my invention.

1 claim:

l. sat'ety closure for containers of inflammable liquids, comprising a shell having a head adapted to be seated Within the neck oi said container and a resilient bulged section below said head that is adapted to trio tionally engage said neck, a reticulated sack depending from the shell-head into the shell, and an openwork thimble extending from the shell-head partly into the sack, said thimble constituting a guard for checking the introduction of a liquid-charging funnel, and constituting likewise exterio-rly accessible means for withdrawing the closure from the container.
